Why Estate Jewelry Appraisals Are Important:

Every piece of jewelry carries both emotional significance and financial value. When it comes to estates, accuracy matters:

  • Estate tax filings & IRS requirements demand appraisals that meet federal standards.

  • Probate and estate settlements rely on fair, transparent valuations to ensure equitable distribution.

  • Heirloom and family jewelry deserves expert assessment to protect legacies and prevent disputes.

At Lauren O Jewels, our estate and heirloom jewelry appraisals combine professional expertise with respect for the stories behind each piece.

How the Estate Jewelry Appraisal Process Works

Our appraisal process is designed to be clear, thorough, and compliant with professional standards:

1. Consultation – We begin with a personalized review of your jewelry and any known history.
2. Examination – Using industry-standard gemological tools, we carefully assess gemstones, diamonds, metals, craftsmanship, and condition.
3. Documentation – You’ll receive a detailed jewelry appraisal report that can be used for:

  • IRS estate tax filings

  • Date of death valuations

  • Probate court proceedings

  • Insurance coverage

Every appraisal is conducted with precision and designed to meet the highest professional requirements for estate planning and legal purposes.
